T2108 too-many-rows
One read of a live query answered more rows than liveRows, which is 10,000 where the project says nothing.
Details
A live query is run again whenever a table it read is written, for everyone who watches it, so one read of it is bounded. The read fails with one row more than the bound. A count is no row, and a query that is not live has no bound of rows.
The fix
State a limit on the plan, and read further pages with after. A query that must answer everything states live: false.
